Scientists hunt mysterious 'dark force' to explain hidden realm of the cosmos

Physicists say a fifth force of nature would 'completely change the paradigm'

Scientists are about to launch an ambitious search for a "dark force" of nature which, if found, would open the door to a realm of the universe that lies hidden from view.

The hunt will seek evidence for a new fundamental force that forms a bridge between the ordinary matter of the world around us and the invisible "dark sector" that is said to make up the vast majority of the cosmos.
